Abstract Microfacies is of great significance in oil field exploitation, because it determines the distribution of reservoirs and barriers of the flow and also controls the fluid flow difference of the reservoir sand. Researches on sedimentary facies are based on the accurate and precise stratigraphic framework model. According to geological characteristics and results of previous studies, the authors used seismic and logging data to identify the thirdgrade sequence boundaries and divided the sequence into systems tracts. On such a basis, the sequence stratigraphic framework of the study area was established, the sedimentary microfacies were divided, and the accurate sedimentary facies model of the study area was constructed through a comprehensive analysis of the single well and logging data.
